TELEPHONE TRANSMITTER MOUNTING-.-

Application filed September 28, 1922; Serial No. 591,016.r

acoustical effects which would distort the sound waves.

In accordance with the general features of the invention a transmitter stand is provided with an enclosure in the center of which the transmitter maybe resiliently supported, the

enclosure havingnonsresonant and non-reflecting walls for affording protection to the transmitter without interfering with the transmission of the sound waves. In its preferred embodiment, the invention provides a drum-shaped cage of foraminated-material such as. metal screen reenforced by slightly heavier "perforated walls togive it sufficient rigidity, thecage being mounted uprlghton a suitable base, 'and' provided with resilient means such as springs for supporting the transmitter centrally within the enclosure.

Referring to the drawings: Fig. 1 is a front view with a section of the face removed.-

Fig, 2 is a side view having a section removed showing the-means for holding the cover on the stand;

On a base 2 is vertically mounted a perforated band 3, preferably of a cylindrical shape, the inner periphery of which is lined with a fine mesh screen 4 extending over the perforations 5. One end of the band 3 is. closed by a foraminated wall 6 andthe other end is closed by a like wall 7. The walls 6 and 7 are preferably perforated frames or plates, lined with screens" 8 and 9,, which cover the perforations therein. One face is removable so as to provide access to the interior of the stand. For this purpose snap clips 10 are provided on thelface 9, which engage corresponding sprmgs 12'on the band 3. A- notch 11 provided en the edge of face 7 ,'engages a pin 16 in the base 2 in order to Within the the face.

57 0,97 0, filed June 26, 1922, is provided .with

a corresponding number of eyes 17 about its periphery. Springs support the transmitter and protect it againstminor as well as major shocks. .The invention claimed is 1. A transmitter mounting comprising an enclosure having a perforated band of cylindrical form, a perforated closure-for-each end of said band, a fine mesh screen completely lining said band and said closures. and shock-absorbing means supporting said transmitter within said enclosure and out of contact therewith.

2'. A portable telephone stand comprising a base, a perforated cylindrical band supported vertically, with its axis horizontal on said base, perforated coverings for each end of said hand, one of said coverings being readily detachable, and means attached to said band for supportingia transmitter against shocks and out of contact with said band and'said coverings.

3. A telephone stand comprising a hase,'a cylindrical band of thin metallic material having large perforations therein, supported vertically with its axis horizontal to said base, perforated truncated cone-shaped front and rear covers for said cylindrical band, a; metallic lining for said band and said covers, covering all openings therein and forming with saidband and covers a nonresonant and non-sound reflecting chamber,

and means attached a to said band for vsupporting a transmitter against shocks and out of contact. with said band and said coverings.

4. A portable telephone stand comprising a substantially cylindrical enclosure, having a perforated cy indrical wall, and c'onicalshaped. front andrearwalls, one of said walls having a relatively large central opening and a plurality of equally spaced marginal openings, a metal gauze lining'for all of said walls and covering the perforated openings therein, and a base for supporting said enclosure.

5. A transmitter mounting com rising a substantially cylindrical. enclosure aving a perforated cylindrical wall, rear and front walls having central and-marginal perfora rations therein, a central perforation being Substantially the diameter of said transmitter, resilient means supporting said transmitter'against external shocks, and coaxial with sand central perforations, gauze covering' the perforations in all Walls, and a base position, and shock absorbing springs atsupporting said cylindrical enclosure with tached to said frame for supporting a transits axis horizontally disposed. niitter in spaced relation With the Walls of (5. A transmitter mounting comprising a said cage.
